But suddenly "npm start" stopped working. I uninstalled everything and tried to reinstall from step 1 given in this tutorial. when i give the command "npm install -g express" i dont get the http 304 and GETS list !! as i ignore and continue the procedure i give npm start command but it doesnt work. the displayed error shows below C: \ project \ nodetest1> npm start

  > nodetest1@0.0.0 start C:\project\nodetest1
  > node ./bin/www

The error indicates that the directory. / bin / www not found. The paths given by dot are relative to the current directory, so for this to work, your current directory must be C: / project / nodetest1 for npm start

.

There are several problems here.

First, you must upgrade to the new one npm

, as the npm

one that comes with the latest version node

is outdated. To update npm

on Windows, follow these steps: https://github.com/npm/npm/wiki/Troubleshooting#upgrading-on-windows

Second, you may need to do a few more problems to find the problem. npm start

just follows the instructions in package.json

. Pack.json tells npm

what it start

means to "run node./bin/www".



What happens if you run the same script from the command line?

cd C: \ project \ nodetest1 node./bin/www

Does bin / www file exist? Is node installed and in your path? These are problems that you will have to fix.

package.json tells npm that the beginning means "run node./bin/www". ** but the packege.json predefined view script is npm run serve **

try this option.

npm run serve

"start": "concurrently \"npm run build:watch\" \"npm run serve\""
